Product Description
For your 2006-2007 Ford F-250, F-350, F-450 and Excursion equipped with the 6.0L Powerstroke diesel engine, the POWERSTROKEPRODUCTS PP-20MMLHDVSO is engineered to deliver serious performance and durability. Built from a brand-new casting (no reman required) and loaded with new valves, seals and heavy duty (100 lb) valve springs, this cylinder head features a machined O-ring combustion sealing surface for improved head-gasket retention under high boost.
This head is ideal for tuned, boosted or high RPM 6.0L builds. The 20 mm dowel fitment ensures correct alignment and installation in trucks built for size-20 dowels, and the O-ring sealing surface keeps compression where it belongs — in the cylinder, not in your cooling system.
Fitment:
- 2006-2007 Ford F-250, F-350, F-450 & Excursion with 6.0L Powerstroke engine (20 mm dowel configuration)
Important Notes:
- Each head is sold **individually** — quantity of 2 required for full engine replacement.
- Use Multi-Layer Steel (MLS) head gaskets only when installing O-ringed heads.
- Hot re-torque after installation is required to maintain warranty coverage.
- Not available for sale or use in California.

FAQ
What makes this head different from stock?
This head uses a brand-new casting (not reman), is assembled with new valves/seals and heavy duty springs, and features a machined O-ring sealing surface to hold compression under high boost.
Do I need to order two heads?
Yes — each head is sold individually. For full engine replacement (both cylinder banks) you’ll need a quantity of 2. Refer to OS to check stock before ordering.
Will it work with any gasket set?
No — due to the O-ring sealing surface you must use MLS head gaskets only. Using Fel-Pro or other style gaskets may void warranty.
Is this legal in California?
No — this product is not available for sale/use in California due to emissions regulations.
